I always preferred money stuff. I feel like the hosts have better chemistry and matt levine is one of the most read/respected financial journalists in the last 20 years. I always look forward to it coming out on a Friday.

Re:Jane Street's Figgie card game

There is a fantastic blog post by Ross Rheingans-Yoo about the shortcomings of poker as a tool to teach trading and why Figgie is a better one. https://blog.rossry.net/figgie/
He also wrote an equally brilliant eulogy about Max Chiswick, one of his colleagues, who helped him develop it. https://blog.rossry.net/chisness/

I wouldn’t be so harsh on him, Karpathy really knows what he’s at when it comes to this stuff. I was sold when I read his recipe for training neural nets.

Re:Ask HN: How do you track user retention metrics?
on Wednesday September 20, 2023 @02:28AM (#37581027)
I’m assuming the issues are encapsulated in the idea that you need to specify what events mean a user is engaged and using a product. Is there not a service which you can send user events to (sign in, interaction with a feature) alongside some sort of unique customer ID? Seems fairly straightforward and would result in a fairly good accuracy considering you can track a user over their entire lifespan.
Is there really no plug n play options?
Ask HN: How do you track user retention metrics?
Hey,I’m looking for a way to track user retention (without a load of hassle) for a side project. How do you guys do it?
Show HN: AI Powered Flashcard Generation

Hey,I'm starting my undergrad degree in CS in a couple of weeks and wanted to build a weekend project. I made Noteform, and it speeds up flashcard creation 10x. Just drag and drop notes and it makes them for you. It also has standard stuff like spaced repetition and CRUD functionality.Have a look.Lewis

Just a note - naming something related to HTTP Express might cause some confusion.
Re:How did Stripe come up with its name? (2015)
on Sunday September 03, 2023 @02:24AM (#37368152)
As per PG: “It turns out almost any word or word pair that is not an obviously bad name is a sufficiently good one, and the number of such domains is so large that you can find plenty that are cheap or even untaken. So make a list and try to buy some. That's what Stripe did. (Their search also turned up parse.com, which their friends at Parse took.)”

Upload all of your course notes onto a website, and have it all categorised and sorted automatically with generated flash cards, key takeaways, etc
Maybe a section for exploring a topic more deeply.

You cannot be serious, this has to be a troll. By pretty much every quality of life index most European countries (esp Western European) rank higher than US. Why do Americans group Europe into one chunk like this? And what exactly is the benefit of income per capita when the environment you have to spend it in isn’t as nice as 90% of European cities/towns?

Right now, I have to remember a large amount of information through rote memorisation. I built myself a little webapp which allows me to upload a folder and it process the text (an un-annoying use of gpt) and spits out gigantic flashcard sets.
